Let w = liters of water needed
4.70= acid in 40% solution 

4.70/70+w  = .28

28=.28.(70+w)
70+w=100
w=30


30 liters of water is needed

Answer:B. 2x^2 + 4x - 1 - 9/4x + 1

Step-by-step explanation:

f(x) = 8x^3 + 18x^2 − 10

g(x) = 4x + 1

We want to determine f(x)/g(x). We would apply the long division method. The steps are shown in the attached photo.

The correct answer is

2x^2 + 4x - 1 - 9/4x + 1
